Method of operating hydraulic bams



UNITED sTATEs PATENT oEEicE.;

CLARK POIJIJEY, OF MAYS LANDING, NEW JERSEY.

METHOD or OPERATING HYDRAULIC.' RAMs.

To all 'whom t may concern.'

Be it known that I, CLARK PoLLEY, of Mays Landing, in the county ofAtlantic and State of New Jersey, have invented a new and usefulSubmarine Hydraulic Ram for the purpose of Elevating Water; and I dohereby declare that the following is a full, clear, and exact.description of the construction and operation-of the same, referencebeing had to the annexed drawings, making a partV of this specification,in whichi Figure l, is a perspective view, and Fig. 2, a verticalsection of the same.

The same letters indicate like parts in both figures.

Where water is to be elevated-from wells or cisterns-to a considera-bleheight, forcing pumps are the machines ordinarily employed; thepractical objections to which Aare their exp'ensiveness and theirliability to frequent and serious derangements, owing to the enormouspressure to which they are subjected.

The object of my invention is to avoid these objections byv substitutingin place of the expensive and fragile forcing pump, the cheap, simpleAand durable hydraulic ram, working in combination with an ordinary andinexpensive suction or lifting pump, and so arranged as practicallytoremove nearly all the strain and wear from the pump to the ram,resulting. in great economy both in power and expense.

The nature of my invention and the manner in which I construct mymachine is asfollows.

In the accompanying drawings, A, Fig. 1, represents an air-tight box orchambersubmerged at the bottom of a well,-within which are inclosed avpump and hydraulic ram; B Fig. 1, represents a coil of pipe, throughwhich flows-from the surfacethe water, by the pressure and momentum ofwhich the ram is to be' operated; C, Fig. 1, represents the conduct pipeconveying the water from the ram to the receiving reservoir; and E, Fig.1, represents a clock work machine (for. which may be substituted otherand sufficient power) so constructedV by means of the connecting rod, R,to work f the pump within the chamber and removing therefrom, ythroughthe pipe D, the waste water of the ram.

The adjustment of the ram and pump within the chamber, A, isrepresented' in Fig.. 2,.whyich-With the-exception of the pipe B beingperpendicular instead of ,i v

coiled-is'an exact vertical section of Fig. l.

Thewater passes from the surface down through the pipe, B, and flows outat H', until suddenly arrested by the closing of the valve it reactsupon itseltand a'portion l is forced into the air-chamber of the ram atH, whence it is elevated by the atmospheric pressure therein, throughthe pipe C, to the i i receiving tank, F. n

The waste water of the ram flows outinto the bottom of the chamber, A,and through the aperture u whence it is removed by the slow and constantaction of 'the pump, O,

operated as beforev stated.

I-do not wish to be confined to the specific mode above described ofadjusting the various parts of my invention, but to retainV to myselfthe privilege of altering these at myk pleasure,.but not in such manneras suby stantially to modify or lchange its character. I do not cla'imin any manner the pump or hydraulic ram, but

What I do claim as my invention anddesire to secure by Letters Patentisy The air-tight box or chamber, A, having within it and incombinationtherewith and with each other-substantially as herein setforth-the hydraulic ram and pump, `and having suitable pipes attached insuch manner as, that` when the apparatus is submerged and the pumpworked from above,

the ram will be free to operate by the pressure and momentumy of thewater resting above it. I i
